movups is slower on older hardware (core2) than movaps, even if the operand is aligned. (Not an issue on modern hardware). Also move i8x16.splat(0x0F) to an external reference so we can load the mask directly.

Since publishing is sequential anyway, we can as well publish all available units in one go. This avoids repeated locking in both the queue and the NativeModule.

(Initially copied from nicohartmann@ CL https://chromium-review.googlesource.com/c/v8/v8/+/2135631) This CL adds a new intrinsic %ObserveNode(expr) which has noop semantics but triggers the new NodeObserver set on the OptimizedCompilationInfo when the node generated for expr is created or changed in any phase (until EffectControlLinearization). This provides the infrastructure to write reasonable unit tests that check for the construction of or lowering to specific nodes (e.g. depending on feedback). When %ObserveNode(expr) is used an object of class ObserveNodeManager is registered to every Reducer/GraphReducer and is notified by the Reducer with all node changes. The same logic is added to classes SimplifiedLowering/RepresentationSelector, which do not inherit from class Reducer. Observed Node modifications currently are: * The Node Operator * The Node type * Node replacements A first use case (cctest/test-sloppy-equality.cc) is included in this CL.

Recompilation for tier down should not be triggered if the module had a compile error. This CL ensures that by moving the recompilation a bit later in the async compilation, to a place where a compile error would have been detected already. An added DCHECK would catch similar bugs earlier (crashing instead of timing out).

The number of old-to-new slots was used as a heuristic in GetMaxConcurrency() to control the number of background jobs.

Due to some unusual build failures on some trybots, v8_generate_external_defines_header was reverted to false. This turns it back on but changes the behaviour so that defines are added to the command line as well as to the header. Because the generated header checks that flags that should be unset are actually unset and flags that should be set are either unset or set to 1, this will cause build failures on many types of mismatches, although it will not detect where a flag is not set on the command line when it is set by the header. If no further failures show up with this, the hybrid part can be removed and the v8-gn.h header can stand on its own.

Writing out the number of functions in the module is unnecessary. That number is only used for validation when reading back the value, but only validating that number is pretty arbitrary and does not protect against bugs or attacks. Hence skip these two header fields.

Holding an unordered set is surprisingly inefficient for large sets. Switching to just a vector makes e.g. deserialization of large modules 30% faster. We pay in terms of memory usage though, so if there is ever a use case where we are storing the same code objects multiple times, we might want do add a deduplication algorithm which cleans up the vector every now and then.

The contract between V8 and Blink is that embedder fields belong to Blink, at least when the object has two or more of them. Now we had 2-3 embedder fields used by the debug proxies and that was confusing Blink, since it expects the first slot to hold an aligned pointer in that case and we had a HeapObject reference stored there. This is a quickfix, which avoids internal fields completely for the context extension proxy (using interceptors on the prototype instead) and changes the named proxies to store the name table under a private symbol instead of using a second internal field. A proper but way more involved fix is to introduce a proper instance type here and use space in the header instead of misusing embedder fields.

In the latest wasm-gc spec, rtts of abstract types are no longer allowed. Consequently, canonical rtts of concrete types always have a depth of 0. Changes: - Change the immediate argument of rtts to a type index over a heap type. Abstract it with TypeIndexImmediate in function body decoding. This affects: value_type.h, read_value_type(), decoding of relevant opcodes, wasm subtyping, WasmInitExpr, consume_init_expr(), and wasm-module-builder.cc. - In function-body-decoder-impl.h, update rtt.canon to always produce an rtt of depth 0. - Pass a unit32_t type index over a HeapType to all rtt-related utilities. - Remove infrastructure for abstract-type rtts from the wasm compilers, setup-heap-internal.cc, roots.h, and module-instantiate.cc. - Remove ObjectReferenceKnowledge::rtt_is_i31. Remove related branches from ref.test, ref.cast and br_on_cast implementations in the wasm compilers. - Remove unused 'parent' field from WasmTypeInfo. - Make the parent argument optional in NewWasmTypeInfo, CreateStructMap, and CreateArrayMap. - Use more convenient arguments in IsHeapSubtypeOf. - Update tests.

On most platforms, we can do a single allocation for all code. On platforms where this is not possible (e.g. ARM64 has a 128MB code space limit), we will at least allocate big chunks instead of one chunk per function. This reduces overhead in {WasmCodeAllocator} for maintaining sets of used and available code space, and reduces locking during deserialization. In order to know how much code space to pre-allocate, the serializer writes out the total code space size. This is then used during deserialization to know how much code to expect.

The same bit field (MiscField) is currently used to encode either a SIMD lane size or a memory access mode depending on the instruction. For now this does not conflict, but in order to support protected loads and stores on arm64, we will need to add a protected access mode to some SIMD instructions that already encode a lane size (kArm64LoadSplat, kArm64LoadLane, kArm64StoreLane). To prepare for this, use non-overlapping bits of the Misc field to encode the two properties.

This change completes support for import assertions for dynamic import(). A new version of the HostImportModuleDynamically callback taking import assertions is added to the public API. The name is very verbose; we could consider removing the "ImportAssertions" part when the old API is removed. Bytecode generation is updated to pass the assertions, if present, to Runtime_DynamicImportCall. Isolate::RunHostImportModuleDynamicallyCallback extracts the assertions from the options bag, filters out the assertions not present in the list specified by the host in HostGetSupportedImportAssertions, and sorts them by code point order of the keys per https://tc39.es/proposal-import-assertions/#sec-import-call-runtime-semantics-evaluation. The resulting array is passed to the host in the callback.

In https://github.com/WebAssembly/simd/pull/423, all any_true instructions were removed, and replaced with a single v128.any_true. This patch removes all but v8x16.any_true, and renames it to v128.any_true.

The change https://chromium-review.googlesource.com/c/v8/v8/+/2572173 implemented HostGetSupportedImportAssertions [1] in a fairly literal sense, where the host supplies a list of supported import assertions and V8 filters the import assertions in a ModuleRequest and exposes only supported assertions via its API surface. However, we've decided that the interop guarantees provided by doing the filtering in V8 are probably not worth the added complexity. Thus, this change removes the filtering. Going forward, hosts will be expected to ignore unknown asserions received from V8. This is mostly a revert of https://chromium-review.googlesource.com/c/v8/v8/+/2572173, with v8::Isolate::CreateParams::supported_import_assertions being kept for now (since we first have to delete the Blink code that sets it), and a new comment in v8.h instructing hosts to ignore unknown assertions.

Prototype these 6 instructions on x64: - f64x2.convert_low_i32x4_s - f64x2.convert_low_i32x4_u - i32x4.trunc_sat_f64x2_s_zero - i32x4.trunc_sat_f64x2_u_zero - f32x4.demote_f64x2_zero - f64x2.promote_low_f32x4 Some of these code sequences make use of special masks, we keep them in external references.
